Thank you. Exactly! I've also learned so much about fixing/troubleshooting from this stuff. It's satisfying to have an outlet for problem solving when there's a fiscal reward attached to it if I succeed. If I don't, then the task is to salvage as much as possible that's valuable and make money from those elements, which can often/ironically be worth more that the entire thing in working order. For example, a complete and working printer can sell for $100, but its printhead will sell for $95. Go figure.

It's depressing, but mostly comical to see why people throw some stuff out when I find and resolve an issue. Many things are actually perfect and were tossed for a replacement as you said, so it's like a 1 inch putt.
